| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | It is necessary to reveal auditory response properties of individual neurons to find out the mechanism of auditory information processing in the brain. The literature has indicated that the auditory response properties are regulated depending strongly on social contexts. Most of the previous studies, however, have not been able to confirm the context-dependent change in auditory neural responses because of the neural recording under anesthesia. In the present study, we recorded neural activities in the auditory cortex of awake freely moving mice, analyzed the auditory responses to various tone stimuli, and calculated spectro-temporal receptive fields (STRFs) and frequency response areas (FRAs) to confirm the context-dependency. We compared STRFs and FRAs of each single or multi units in two different social context: “social condition” with a stimulus mouse and “alone condition” without the stimulus mouse in the cage. We found that STRF’s response area reduced especially along temporal axis in “social condition” than that in “alone condition”. This result suggests that temporal selectivity to sound stimuli increased depending on social context in the mouse auditory cortex. Such essential investigations for context-dependence will help us to understand the mechanism of adaptive auditory processing in the brain according to various social contexts. | |
